To aZZ whom if may concern:

Be it known that l, FRANZ BOSCH, a sub ject of 'the King ofr Bavaria, residing at Munich, Bavaria, in the Empire of Germany, have invented certain new and useful lmprovements in Devices for Facilitating Teething in Childreln'of which the following is a speciication.

The development of the teeth, which, with children, is always attended with disorders and illness, demands an increased supply of salts of calcium to the gums. According to the mannerand the quantities in which this disorders and symptoms of disease are mani- The object of the present invention is to supply, the gumsv with salts ot' calcium not only in the natural manner, but also by arti* ficial means, and thereby to assist or facilitate dentition as much as possible. For this purpose a device embodying my invention consiste in the means, features and combinations of parts hereinafter set forth and pointed out in the claims.

In the accompanying drawings-Fieure l represents a longitudinal central section 3 and Fig. 2 a side elevation, partlyin section, ot a teething device under my invention; 3 a similar view ot'` a modified form of teething device; and Fig. i a frontelevation thereof.

In all the ligures the same letters of reference designate the same parte.

The'device made under any invention is in teething rings, consisting broadly of a stirr-np or mouthpiecea, of rubber or other suitable is in the form of the ,gein and is prei-dried on both sides with recesses or depressions of embrace the gums. These recesses, as shown cite the tooth -germs when the stirrup is, grasped bet-Ween the gums. 'ihe stirrnp is provided with a handle and a safety-disk, b, in the manner of the well-known teething rings, the said safety-disk obviating the dann ger of swallowing the device.

he stirrup or mouth-piece 'when usedhas a calcium salt applied thereto and for this purpose may be coated or painted with a liquid containing lime or calcium-salts and then introduced between the gums of the infant. In order to enhance the supplyof these salts the followingadditional means are resorted to.

As. shown in Figs. l and 2,the month-piece, a, is hollow or provided with a cavity, e, con;4 taining a sponge, f, or other porous and absorptive body. A duct or tube, c, adapted to be closed at its outer end by a stopper, c', `communicates with the cavity, e, and serves to supply the latter with the solution of cal` cium salt. yThe month-piece is provided with lateral slits (indicated in dotted. lines in Fig. 6 5 l) or perforationsa 2, through which the liquid 'can escape to the outside and into the rocesses on either side ofthemouth-piece, by virtue of the pressure of the gums or the suction which the infant or child exerts when the mouth-piece is introduced between the gums. In Figs. 3 and 4 a modification is shown `which in all respects is substantially similar to that in Figs. l and 2, with the exception that the mouth-piece is there provided With'a longitudinal or meridianal slot, d, through `rhich the calcium-salt -solution is admitted to, the interior cavity, e, and the absorptive body, f. 'When the mouth-piece under this construction is grasped between the gums, the sicuri, is closed and the absorptive body f, is compressed and the liquid it contains'is caused to flow out ofy the same through the perorations, a, to the gums. In this moditication the duct, c, is permanently closed at its outer end.

It is manifest that this device may be modiiied in many particulars without departing from the principle cmy-i invention. Thus for example the material of which the monthpieee, a, is composed mayitself he treated or impregnated wit-han addition 'cla calcium Compound. A

What l claim, and desire to secure by Let ters Patent, lis r l.. in a teething ring a hollow mouthpiece having openings through its walls, and an absorptive body 'within 4the month-piece, snb-v stantially as set forth.

2. In a teethingring, a month-piece having 1 oo ma m'po oi the gums and provided with wema y ,on both sides, auostauioily as set 5. A teething ring hvnga mouth-piece in the shape of the gums sind provided on both sides with roughened recesses as g, snbstanr 5 iaiiy :is set for-th.

' ln testimony than; claim the foregoing as my invonton 1 havo signed. my nanna in presence of two subscribing winessas.
